A trunk inspection control system for detecting line acquisition and line recovery by detecting the voltage and current of the line SL, wherein the level of the voltage and current of the tip line TL, the ring line RL, and the sleeve line SL is controlled. The microcomputer 5 controls the entire system, a relay driver 6 for driving the relays RY1-RT4 on and off by driving the control signal of the microcomputer 5, and after the subscriber line is captured, the relay ( The discharge section 9 for discharging the charge remaining in the tip line TL and the ring line RL according to the on-off switching of RY3, and the on-off switching of the relay RY4 after the residual charge discharge. Voltage sensing to detect the voltage of tip line (TL) ring line (RL) and the subscriber's call 7, a trunk inspection of an electronic exchange control system, characterized in that configured as 8. 회선포착시 마이컴 (5)은 팁라인 (TL) 및 링라인 (RL)을 단락하고 릴레이 (RY1)를 턴-온시켜 슬리브라인 (SL)을 소정시간 전류감지부 (4)에 접속하고 소정시간이 경과되면 릴레이(RY2)를 턴-온 시켜 슬리브단자 (SL)를 전류감지부 (3)에 접속한 후 팁단잘 (RL)및 링단자(RL)의 역전압을 체크하여 역전압이 없으면 소정횟수로 반복검출하고, 역전압이 있으면 다이어링을 수행함과 아울러 릴레이 (RY2)를 턴 -온 시켜 슬리브라인 (SL)을 다시 전류감지부 (4)에 접속한후 그 슬리브라인 (SL)에 흐르는 전류를 체크하여 전류가 없으면 소정횟수를 반복검출하고, 있으면 팁라인 (TL), 링라인 (RL)을 개방하여 그 팁라인 (TL) 및 릴라인 (RL)에 잔류하는 전하를 방전부 (9)로 방전시키고, 이후 마이컴 (5)은 팁라인 (TL) 과 링라인 (RL)의 전압을 전압감지부 (2)로 부터 검출하여 전압이 있으면 통화상태로 판단하고 없으면 회선포착을 완료함과 아울러 팁라인(TL)링라인(RL)을 단락시키고 전압감지부(7)(8)을 턴-온시킨후 원격자동검침을 수행하여 팁라인(TL)및 링라인(RL)에 전압이 있으면 회선복구를 수행하고 없으면 검침을 완료하는 것을 특징으로한 전자교환기의 트렁크 검사 제어방법.At line acquisition, the microcomputer 5 shorts the tip line TL and the ring line RL, turns on the relay RY1, and connects the sleeve line SL to the current sensing unit 4 for a predetermined time, After the elapse of time, the relay RY2 is turned on to connect the sleeve terminal SL to the current sensing unit 3, and then the reverse voltages of the tip terminal RL and the ring terminal RL are checked. Repeated detection is repeated for the number of times, and if there is a reverse voltage, dialing is performed and the relay RY2 is turned on to connect the sleeve line SL to the current sensing unit 4 again, and then flows into the sleeve line SL. The current is checked and a predetermined number of times are repeatedly detected if there is no current. If there is a current, the tip line TL and ring line RL are opened, and the charge remaining in the tip line TL and the reel line RL is discharged. ), And then the microcomputer 5 detects the voltages of the tip line TL and the ring line RL from the voltage sensing unit 2, and there is a voltage. If it is not determined to be in a call state, the line acquisition is completed, the tip line (TL) ring line (RL) is shorted, the voltage sensing unit (7) (8) is turned on, and the remote automatic metering is performed to perform the tip line ( TL) and ring line (RL), if there is a voltage to perform the circuit recovery, if not, the trunk inspection control method of the electronic switch characterized in that the completion of the meter. ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.※ Note: This is to be disclosed by the original application.
